ultrasonic sonochemistry machine

Ultrasonic welding machine is a common mistake, using ultrasonic welding equipment of all kinds of plastic parts are quite popular, packing of the products. Cutting. Riveting for burial. Embossing. Punch.
Quite many years engaged in the personnel ultrasonic welding, etc. For ultrasonic sonochemistry machine ultrasonic energy transfer is a myth, that is in the welding of the contact area, in fact this is a myth, the real welding principle is: mechanical sensor power conversion, through the conduction workpiece materials, sound waves in the solids occurs, the conduction resistance is far less than the acoustic resistance in air, when the sound waves through the workpiece joint, crack in the acoustic resistance is big, the heat energy is considerable. Temperature to reach the tolerance of the workpiece and point, add pressure, seam welding. And artifacts due to other parts of the small heat resistance, low temperature welding.
Ultrasonic welding machine welding material, not all of the material can be ultrasonic dispersion machine welded, someone for any material can understand welding, this is a big mistake. Some welding between different kinds of materials, have a plenty of the primary stage, have a plenty of have no melting stage.
Ultrasonic mold dynamic node design, welding head, the amplitude is designed as a work of half wave resonance frequency, in working status, the amplitude of two end face is big, small stress, and equivalent to the middle nodes of the amplitude is zero, the stress.
General design for fixed node position, but usually the fixed position of the design thickness is greater than 3 mm, or groove is fixed, so the fixed position is not zero amplitude, this will lead to some calls, and part of the energy loss, for sound usually with a rubber ring with the other parts, or block with sound insulation materials, and energy loss in the design of the mould be considered amplitude parameters.
Ultrasonic welding machine welding parts process error, Yu Chaosheng ultrasonic dispersing machine energy transfer is a myth, that is the contact area in the welding shape, actually this is a myth
Ultrasonic energy is an instant burst, melting into it should point or line, and the transmission distance must conform to the way of ultrasonic welding. Some people think that as long as it is plastic material, no matter how can be welded joint surface is good, this is a mistake. When the instantaneous energy to produce, the joint area is larger, the more severe energy diffusion, the welding effect is poor, even can't welding. Another is the ultrasonic longitudinal wave, energy loss is proportional to the distance, long distance welding should be no more than 6 cm to control. Welding line should be appropriate, 30-80 line between workpiece arm was controlled in not less than 2 mm thick, or bad welding, especially for the sealing products.
